Saint Catherine of Siena MC, located in Riverhead, New York, offers Partial Hospitalization Program (PHP) services, one of just seven facilities among 56 nearby to do so. This level of care allows people to receive structured daytime treatment while continuing to live at home, an arrangement that can suit older adults and others who need consistent support without a residential stay. The program includes experiential therapy as part of its treatment approach.

The facility works with people addressing self-harm and accepts Medicare, with sliding scale payment options available for those who qualify. It is set up to serve seniors aged 65 and older among its clientele. Vaping is permitted on site, a policy detail that may matter to those weighing daily comfort during treatment.
